4 claims. (o1. 221-95) l 'Ihis invention relates to a dispensing pump of a type used for dispensing gasoline to motor vehicles at service stations, and is more particularly concerned with a novel mechanism for controlling the starting and stopping of the pump which is driven by an electric motor, and for rendering it impossible to start the pump when the delivery nozzle of the apparatus is locked in place on a pivotally mounted supporting hook member therefor, the movement ofthe member being what is used to control the starting and stopping of the motor which drives the pump.

The invention consists of many novel organizations and arrangements of parts for the attainment of the end stated and for the attainment of numerous other ends and results not at this time specifically enumerated, but which will appear fully and in detail upon an understanding of the invention had from the following description,

taken in connection with the accompanying drawings, in which,

Fig. 1 is a partial vertical section and elevation of a gasoline pump structure made in accordance with my invention, and

Fig. 2 is a fragmentary View, similar to that shown in Fig. 1, but with the delivery nozzle detached from the supporting hook member therefor and turned to a position to start the motor.

Like reference characters refer to like parts in the figures of the drawings.

The mechanism of the gasoline pump is almost entirely enclosed within a suitable housing having a lower vertical housing member 1, a frame 2 at the upper end of the housing 1, and an upper sheet metal housing member 3 of a smaller size which is capped at its upper end with a cap 4.

The pump 5 for pumping the liquid is located within the lower housing member 1 and is adapted to be driven by an electric motor 6, drawing liquid through an inlet pipe 7 which extends downwardly to a main supply tank and forcing it outward through an outlet pipe '8 which extends vertically and in its length has a valve casing 9, the upper end of pipe 8 connecting by an elbow 10 which leads to a suitable meter 11 for measuring the gasoline, after which it passes outward through a pipe 12 which extends through a side of the upper housing member 3 and empties into thelower end of a vertical glass cylinder 13 at the outside of the housing member 3. A

, delivery hose 14 connects with the lower end of the cylinder. It may be of any suitable length, and at its free end carries an elongated valve controlled delivering housing 15 to which a flexible nozzle member 16 is secured. A valve within the housing 15 normally obstructs the passage of liquid therethrough. A valve operating stem 17 extends to one side of the housing and by pressing thereagainst the valve may be opened for the passage of the liquid. An open bracket 18, of the shape best shown in Fig. 2, is connected integrally, preferably, with the member 15 extending around the valve stem 1'7 and at its lower side being slotted as indicated at 19. A hand operated lever 2O is pivotally mounted at one end at 20a on the member 15 and extends across the projecting end of the stem 17 in a position such that by grasping the housing 15 below the valve and engaging the fingers with the free end 70 of the lever 20 the valve may be moved to open position.

A nozzle supporting lever 21 is pivotally mounted between its-ends, at 22, on a suitable support within the housing member 3, said lever extending through an opening in the housing member and at its outer end being formed into hooks .23 separated from each other, and having lug 24 with an opening through it at its upper side located between the hooks 23 and the adjacent 90 side of the housing member 3. The lug is of proper thickness to pass through the slot 19 in the bracket 18 previously described when the bracket is located over the hook 23 of member 21 as shown in Fig. 1. The vertical side of the bracket 18 bears snugly against an outer side of the housing member 3 and the flexible nozzle 16 is passed throughan opening 16a (see Fig. 2) in the member 3. ,Any suitable padlock (Fig. 1) may then be passed through the opening in the lug 24, locking the parts in position so that they cannot be disengaged from each other and locking the lever 21 against movement. The lever in such a position, as shown in Fig. 1, is at its lowermost position at its outer free end and 95. cannot be moved upwardly because such movement is stopped by the engagement of the nozzle member 16 with the housing 3 through which it passes. k

The inner end of the lever 21 is pivotally con- 100 nectedV wtih the upper end of a vertical rod 25 y which extends downwardly alongside of pipe 8.v It carries a laterally extending bracket 26 having a projecting finger 27 at its free end engaging with a movable plunger 28 of an electric switch 105 29 interposed in the electric circuit which controls the operation of the motor 6. Cables 30 indicate where the electric circuit wires run connecting with the motor an overhead light above the cap 4. In the position of a lever 21 shown in Fig. 1 110 v the switch plunger 2,8"is moved to upper position and the circuit to the motor is broken. But when the nozzle member' is disengaged from the hook.

lever or support 21 it may be turned upwardly, as shown in Fig. 2, throwing the switch plunger 28 to operative position, completing the circuit and thereby starting the motor 6 in operation.

Two spaced apart collars 31 are i'lxed on the rod 25 at a side of the valve housing 9 previously described. A valve operating handle 32 with a shut-oil valve in housing 9 to operate the same to open or closed position extends under the upper collar 31 and rests against a. coiled spring 33 around rod 25 and above the lower collar 31,. When the lever 21 is turned to its operative position (as in Fig. 2) the shut-0E valve in housing 9 is opened for the passage for liquid from the pump and it is closed when the rod 25 is moved vertically. The valve 9 serves to positively stop the ow from the pump by depression of the lever 21 so that in case of breakage of the hose 14 or failure ofthe switch 29 to operate the valve 9 may be closed to stop waste of gasoline. The pipe 8P leads to an expansion chamber 8b.

With the construction described, when gasoline is to be delivered to, a customer the member 18 is disengaged from the lever 21 and the motor started in operation by the operator manually throwing the lever to upper position .shown in Fig. 2. The operator actuates the lever 20, watches the meter tosee that the proper amount is pumped, releases the lever 20 when such an amount has been' pumped, and then hangs the nozzle on the hooks at 23, this causing the lever 21 to take its lower position and stop the motor through opening the switch and at the same time closing the shut-off valve at 9. The bracket 18 is provided with a hook 1.8 which may be engaged over either of the hooks 23 when the pumpy is in service during the day, but at night when the pump is to be locked against operation by unauthorized persons the nozzle 16 is inserted through theA opening 16a, the lug 24 passing through the slot 19 `and the padlock shown in Fig. 1 connected with said lug.

The .construction described is relatively simple but is very practical and emcient for the purposes for which it is designed. It is evident that no gasoline can be delivered unless the switch can be operated and it is further evident that when the parts are locked in position as in Fig. 1, no operation of the lever 27 can take place. The invention is defined in the appended claims and is controlling the operation fr the electric motor,

a. pivot'ally mounted leverfextending through a side of the housing on which the hose is adapted to be carried, said housing having anA opening through which the free end portion of the hose may be passed into the housing, a rod connected to said lever and to the switch for moving the switch to inoperative position when: the hose is placed on the lever, .said lever being adapted to be turned to a position to move the switch to operative position when the hose is disconnected from the lever.

2. In a construction of the class described, a hollow housing, a rotary pump mounted therein, an" electric motor for driving the same, a lever pivotally mounted between its ends above the pump having a free end portion extending through a side of the housing, a rod connected to the lever, a switch for controlling the operation of the motor actuated by movements of the rod, a conduit for carrying liquid pumped by the pump, a nozzle member secured to the free end of the conduit having a flexible free end portion, and a bracket secured to the nozzle member adapted to seat on said lever and bear against a side of the housing, said housing having an opening through which the exible free end portion of the nozzle passes when thus seated, the weight of the nozzle member on said lever serving to move the same and operate the switch to a position for stopping the motor. v

3. A construction containing the elements in combination dened in claim 1, combined with a valve housing interposed in the length of said conduit and located alongside of said rod, said housing having a valve therein, means on said rod and means connected with said valve cooperating with the first means to move the valve to open position when the motor is started and to closed position when the motor is stopped.

4. In a construction oi the class described, a rotary pump, an electric motor for driving the same, a switch for starting and stopping the motor, a lever pivotally mounted between its ends having an outwardly extending free end portion, a rod connected to the other end portion of th lever and operatively associated with said switch to turn it to motor startingrand stopping positions, a conduit for carrying liquid pumped by said pump including a flexible hose, an elongated valve housing connectedl to the free end of the hose, a bracket secured to and projecting from one side of the housing, adapted to rest on the outwardly extending free end portion of the lever, a lug on said lever, said bracket having a slot through which the lug passes, a valve in said housing, a piv'otally mounted handle for operating'the valve and adapted, at its free end, to come against the lug when the bracket is placed on the lever and be held for movement, an enclosing housing for the pump, motor, switch, and said rod, through a side of which the lever extends and against the sam'e sideof which said bracket bears, said enclosing housing having an opening above .the

lever, and a exible delivery nozzle portion conl nected to said valve housing extending through said opening.
